How to Enhance the Performance of your React
Native Mobile Application

• By Beyond Root Technology Services

Introduction

• Over the last few years, React Native has
  escalated the mobile app development to an
  unprecedented level. It turned into a boon for
  businesses by enabling them to rationalize costs,
  facilitate market penetration, and develop highly
  responsive user experience. These advantages have
  been impactful enough to steer big brands like
  Facebook, Instagram, Walmart, Tesla, Uber, and
  more towards React Native app development.
  Furthermore, this framework has also stimulated
  SMEs to hire React Native app developers and
  yield these benefits.
• Since building an app, testing it, optimizing it
  and launching it are the keys to creating a
  consistent user experience, below are some of the
  powerful ways to improve the performance of your
  app and get the most out of it.

Include only necessary features

• A long feature list may cause your application to
  suffer slow display times. If you want your app
  to perform swiftly, eliminate all the unnecessary
  data, animations, controls, tabs, and
  navigations.
• Make sure to display the required features only
  as they have the potential to expand the display
  times of your app and result in cluttered user
  experience. A lean architecture will help your
  app fly.

Focus on app launch time

• If your apps launch time is too slow, users
  wont give your app a single chance. The key
  reason for this issue is object.finalize.
• Finalizers run on the main thread and can lead to
  error messages that show your app is running out
  of memory, even when there is enough RAM
  available.
• This is one of the primary reasons for the high
  launch times of your React Native app. To avert
  these issues, avoid using Object Finalizers and
  running essential components on the main thread.

5
Prevent memory leaks

• Memory leaks have always been a critical issue in
  Android devices, which often happen when too many
  unwanted processes run in the background. In
  these issues, the application is closed while the
  memory isnt released, and hence, in the next
  launch, additional memory allocates.
• One of the best ways to overcome memory leakage
  is to use scrolling lists like SectionList,
  FlatList, or VirtualList, instead of ListView.
  These listing components will prevent memory
  leakage, provide smooth scrolling, and optimize
  the overall performance of your React Native
  mobile application.

6
Reduce app size

• Most apps built using JavaScript use native
  components along with some third-party libraries.
  Higher the number of components and libraries,
  the larger the app size.
• To reduce the app size, ask the experts of
  the React Native App Development Company you
  hired to use only essential components, optimize
  them, reduce graphics size, and use an optimizer
  like ProGuard. Reducing the app size will also
  reduce its download time and improve its
  performance considerably.

7
Use rendering carefully

• Excessive component rendering can impact the
  performance of your app negatively. To avoid such
  cases, do not incorporate different state of the
  props and life cycles. It is vital to ensure that
  the reconciler is not overloaded with unwanted
  work. This can decrease the per second output of
  JavaScript threads frames, which may reduce the
  apps speed.

8
Optimize images

• Images consume a significant part of your app
  memory. To enhance the app performance, optimize
  the size of the images using services like
  TinyPNG before using them in the app.
• Besides, we recommend using webP format for JPG
  and PNG files to improve app loading speed up to
  28 and reduce iOS and Android binary sizes by
  25.

Conclusion

• React Native is a complex platform in terms of
  its architecture and different libraries,
  components, and Native Modules. But, ever since
  its inception, a plethora of organizations have
  trusted this framework to develop their apps as
  it is rewarding in many aspects.
• If youre also devising to hire React Native app
  developers to give a mobile presence to your
  business, take these issues and their
  countermeasures into account before embarking on
  your cross-platform app development journey.
